Perhaps you should try some spelling variations:
financial statements » financial management
financial surveys » financial service, financial burden, financial studies
financial systems » financial system
financial stress » financial distress, financial access, financial strength
world economic » world economy
services » series

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: "((\"world economic AND ((((financial surveys) OR (financial stress))) OR (financial services)).\") or (((\"world economic AND financial systems.\") or (\"world economic AND financial statements.\"))))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"world economic and ((((financial surveys) OR (financial stress))) or (financial services)).\\") or (((\\"world economic and financial systems.\\") or (\\"world economic and financial statements.\\"))))\"".
• Removing quotes may allow a broader search: (( world economic and ((((financial surveys) OR (financial stress))) or (financial services)). ) or ((( world economic and financial systems. ) or ( world economic and financial statements. )))).
